Check clearances given on the outside of each burner to make sure the product is suitable for your application. 3. Installer must be a trained, experienced service technician or representative. 4. All service must be performed only by a trained service technician or representative. 5. After installation is complete, check product operation as provided in these instructions. Combustibles: Failure to maintain the specified minimum clearances to combustibles could result in a serious fire hazard. Do not locate flammable or combustible materials within this distance. Signs should be posted in storage areas to specify maximum stacking height to maintain required clearances to combustibles. Do not locate in hazardous atmospheres containing flammable vapors or combustible dust. United States: Installations in public garages or airplane hangars are permitted when in accordance with ANSI Z83.6 and NFPA-409 and 88 Codes. Canada: Installation in public garages is permitted when in accordance with CAN/CGA B.149.2. Installation in airplane hangars is permitted when in accordance with the requirements of the enforcing agency. Vehicles: Minimum clearances must be maintained from vehicles parked below the heater. Ensure that adequate clearance is maintained where vehicle lifts are in operation. Gas Connection: There is an expansion of the radiant pipe with each firing cycle, and this will cause the burner to move with respect to the gas line. This can cause a gas leak resulting in an unsafe condition if the gas connection is not made strictly in accordance with Figure 27 of these instructions. Ignition: This appliance does not have a pilot. It is equipped with an ignition device which automatically lights the burner. Do not try to light the burner by hand. Mechanical Hazard–Suspension: Use appropriate suspension hardware, beam clamps (rod or perforated strap) and turnbuckles at predetermined locations. The weight and normal movement of the heating system may cause support failure if the following minimum suspension requirements are not met: distance between supports must be 10 ft. (3 m) or less; chain must be general purpose proof coil steel chain, 3/16" (5 mm) or larger in Diameter, with a working load limit of a mimimum of 750 lbs. Failure of the WARNING Failure to follow these instructions can result in personal injury or property damage: Do not use in an atmosphere containing halogenated hydrocarbons or other corrosive chemicals. Some compounds in the air can be drawn into the equipment and can cause an accelerated rate of corrosion of some parts of the heat exchanger. The use of such chemical compounds in or near the enclosure should be avoided where a longer life of the burner, tubing and other parts is desirable. Caution should be used when running the system near combustible materials such as wood, paper, rubber, etc. Consideration should be given to partitions, storage racks, hoists, building construction, etc. Figure 1 gives minimum acceptable clearances to combustibles. If the building has a slight negative pressure or contaminants are present in the air, an outside combustion air supply to the heater is strongly recommended. CAUTION Failure to follow these instructions can result in damage to the system components: Do not high pressure test the gas piping with the burners connected. Failure to follow this procedure will exceed the pressure rating of burner gas controls and this will require complete replacement of these parts. This heater is designed for heating nonresidential indoor and outdoor spaces. These instructions, the layout drawing, local codes and ordinances, and applicable standards that apply to gas piping, electrical wiring, venting, etc., must be thoroughly understood before proceeding with the installation. WARNING Improper installation, adjustment, alteration, service or maintenance can result in death, injury or property damage. Read the installation, operation and service manual thoroughly before installing or servicing this equipment. For assistance or additional information, consult a qualified installer, service agency or your gas supplier.

Introduction Roberts-Gordon pioneered low-intensity infrared heating systems in 1962 with the introduction of its revolutionary custom-engineered CORAYVAC ® system. In 1973, Roberts-Gordon expanded its product offering to include unitary heating systems. The VANTAGE® product line was first introduced to North America in 1987 and since its inception, the product has been setting the standard in unitary infrared heating. The VANTAGE ® HE, introduced in 1998, is a noncondensing, field assembled unitary heating system that is approved for outdoor and indoor installations. Easy to install, this system requires minimal maintenance and is effective in moist or mildly caustic environments due to extensive use of corrosion resistant components. It is designed to provide years of economical operation and trouble-free service. Checking Shipment Check the shipment against the Bill of Lading for shortages. Also, check for external damage to cartons. Note any shortages, and/or external damage to cartons on the Bill of Lading in the presence of the carrier. The carrier should acknowledge any shortages or damage by initialing this “noted” Bill of Lading. Immediately report any claims for damaged material, or shortages that were not evident at the time of shipment, to the carrier and your Roberts-Gordon Factory Representative. Installer Responsibility All heaters and associated gas piping should be installed in accordance with applicable specifications and this installation made only by firms (or individuals) well qualified in this type of work. Consult local Building Inspectors, Fire Marshals or your local Roberts-Gordon Representative for guidance. VANTAGE ® HE heaters are installed on the basis of information given in a layout drawing, which together with the cited codes and regulations, comprise the basic information needed to complete the installation. The installer must furnish all needed material that is not furnished as standard equipment. It is his responsibility to see that such materials, as well as the installation methods he uses, result in a job that is workmanlike and in compliance with all applicable codes. The VANTAGE® HE heater has been extensively tested under extreme conditions and is highly resistant to the outdoor elements. Care must be taken to design the proper hanging brackets and suspension (see Figure 14b) of the unit in high wind areas; care must also be taken to keep the burner section out of the direct spray of pressure wash in a wash bay. Roberts-Gordon Factory Representatives have had training and experience in the application of this equipment and can be called on for suggestions about installation which can save material and money. Section 3. Planning The following codes and instructions should be followed when planning the installation of the heater.

Where there is the possibility of exposure to combustible airborne material or vapor, consult the local Fire Marshall, the fire insurance carrier or other authorities for approval of the proposed installation. pg 4 VA N TA G E ® HE ROBERTS-GORDON I N S TA L L AT I O N M A N U A L Critical Considerations WARNING Installation Procedure WARNING Several steps are involved in the installation of the heater. Do not attempt to operate the heater until all steps of the installation have been accomplished. Fire Hazard Some objects will catch fire or explode when placed close to heater. Keep all flammable objects, liquids and vapors the required safe distances away from heater. Failure to follow these instructions can result in death, injury or property damage. ATTENTION Risque dincendie Certains objets placés près du radiateur peuvent senflammer ou exploser. Tenir tous les objets, liquides et vapeurs inflammables à la distance de sécurité requise du radiateur. Le non-respect de ces consignes peut causer mort, blessures ou dommage matériel. The Vantage® HE is a suspended heater. Therefore, its stability, flexibility, and safety are very important. Before starting installation, be sure the system can meet the following requirements: • Maintain specified clearances to combustibles, and safe distance from heat-sensitive material, equipment and work stations. • Provide a suspension with vertical length of chain or swinging rod which has at least 2" (5 cm) of horizontal travel for each burner in a straight run. Be sure the suspension system is sufficiently flexible to accommodate thermal expansion which occurs as the system heats up (see Figure 15). • Outdoor hanging: Chain should not be used when installing the unit outdoors. Use a suspension system which minimizes the lateral movement or swing which might damage reflectors. See Figure 14b for further details. • Washbays: The VANTAGE® HE unit must not be exposed to the direct spray from a pressure washer. • Provide access to burners for servicing, preferably on both sides, above, and behind for burner removal. • Be sure the heater has a downward pitch of 1/2" per 20 ft. (1 cm per 6 m) away from the burner. • Provide signs in storage areas to specify maximum stacking height to maintain required clearances to combustibles. • Plan location of supports. Locate a support near all elbows. • A minimum of 10 ft. (3 m) on HE-60/80 and a minimum of 15 ft. (4.6 m) on HE-100/125/150/175 is required between the burner and the first elbow. Failure to follow these instructions can result in death, injury or property damage. Take maximum advantage of the building's upper structure, beams, joists, purlins, etc., from which to suspend the heater. There is no unique sequence for installation of the tubing. On-site observation will usually reveal a logical sequence. Begin the installation at the most critical dimension. This could save time. Watch for swinging doors, overhead cranes, car lifts, etc. Reflectors and tubing can be installed as you move along. Carefully adjust system pitch at each position to level the heater. Pitch down 1/2" per 20 ft. (1 cm per 6 m) away from burner. Outdoor Mounting: The VANTAGE® HE unit is meant for stationary mounting in all situations and should not be suspended from any structure which may become mobile or from any organic structures such as a tree. Clearances to combustibles must be maintained in all cases; do not install heaters in a location such as a parking area, where a vehicle with a painted or nonmetallic upper surface, may be parked within the clearances to combustibles. The bottom of the combustion air inlet shall not be less than 12" (30 cm) above a surface which could support snow, ice, or debris. Do Not: • Pressure test the gas line using high pressure (greater than 1/2 PSIG) without closing the high-pressure shutoff cocks. Failure to do so will result in damage to the burners. Do: • Familiarize yourself with local and national codes. • Develop a planned procedure which will conserve material and labor on the job. • Check to see that all material and equipment is on the job before starting installation. • Allow for thermal expansion of the hot tube. • Install the gas connector only as shown in instructions (see Figure 27). • Have slip joints where required between reflectors to keep them from buckling or coming apart.

Component Installation TUBE COUPLING INSTALLATION Tube and tube fittings are connected by wrap-around couplings which clamp by means of a tapered, hammerdriven lock member. Loosen Tighten Impact Block Use a 4 ft. (1.2 m) level as indicated to establish pitch of tubing and to ensure that tubes fit squarely at ends. This in turn will ensure the proper fit of couplings. Figure 8b. Level Tubing Slide Bar Carriage Bolt Stainless Steel Coupling Transition tube Flat washer and hex nut Lanced Clip When assembling coupling, the wide end of the slide bar moves toward the lanced clip CL Tube clamp Orient coupling so that the impact block is above tube centerline. Burner assembly Figure 8a. Coupling Assembly To assemble the coupling, hook the free end of the coupling sleeve into the lanced clip. Place the wide end of the tapered slide bar on the coupling so that it moves toward the lanced clip. Insert the two tube ends into the coupling. Be sure the tube ends are in line and are flush against the stop pins inside the coupling. Hammer-drive the slide bar until the coupling is secured snugly to the tubes. Overdriving the slide bar will distort the coupling or slide bar lip and will decrease the holding capability of the coupling. Coupling should be tight when the slide bar is ± 2" (5 cm) from the end of the coupling. See Figure 7a. Position tube and reflector hanger no more than 4" (10 cm) away from the burner assembly.

Typical Suspension Details for Indoor Installation Only TURBULATOR INSTALLATION For ease of installation, the turbulator should be installed in the tube before hanging the system. Use the following procedure (see Figure 17): 1. Assemble turbulator pieces by “twisting” matching ends together. 2. Insert a long wire (11 ft. (3.3 m) minimum) down the length of the tube. Attach the wire to the hole in the tab on the adapter piece. 3. Using the wire, pull the assembled turbulator into the tube from the opposite end. Pull the turbulator through until just the tab comes out. Detach the wire. 4. Bend the tab around the tube. When installed, the vent adapter will lock the tab in place. Attach a wire to this tab.

Turbulator Baffle Assembly Detail pg 20 VA N TA G E ® HE ROBERTS-GORDON I N S TA L L AT I O N M A N U A L SIDE EXTENSION REFLECTOR (Not for Outdoor Use) Optional Side Extension Reflectors may be installed on either side of the unit. Each 8 ft. (2.4 m) section of Side Reflector should match a reflector and have identical overlap to adjacent reflectors. Provide slip joints in the same locations as the reflectors. Proceed as follows (see Figure 18): 1. Attach a reflector side extension support bracket to the tubes where needed. These brackets should be located adjacent to the overlapped joints of the reflectors. 2. Inser t lower edge of reflector side extension in extension support bracket. 3. Cut suitable relief notches where the side extension reflector meets tube and reflector hangers and reflector support brackets. 5. A slip joint must be provided in the perimeter side extension at the location of each slip joint in the reflector. The overlap should be the same as the reflector. 6. Where severe air movement may be encountered, as at a large door, one or two sheet metal screws should be used to attach the side extension reflectors together. Additional reflector suppor ts are also recommended. 7. To Install the Retainer Clips: Lay bracket over the side extension reflector and standard reflector at the selected location. By using the hole in the clip as a template, drill or punch a 3/32" (2.4 cm) diameter pilot hole in the standard reflector. Secure the retainer clip using #8 x 3/8" sheet metal screws. 4. Hook the top edge of the side extension reflector over the edge of the reflector. #8 x 3/8 Sheet Metal Screw Retainer Clip Tube and Reflector Hanger Stainless Steel Reflector Relief Notch Tube Not Shown Reflector Support Stainless Steel Reflector Side Extension Side extension reflector support bracket Stainless Steel Reflector Side Extension Package (P/N 027127SS) includes: (1) Side Extension Reflector, (2) Retainer Clips and (2) Sheet Metal Screws.

Non-Pressurized Outside Air Supply for Single Heater Installations OUTSIDE COMBUSTION AIR SUPPLY IMPORTANT: If the building has a slight negative pressure or contaminants such as halogenated hydrocarbons are present in the air, an outside combustion air supply to the heaters is strongly recommended. The VANTAGE® H E heater is approved for installation with an outside air supply system. An outside air supply should not be used with the draft hood venting configuration. For an outside air supply, a 4" (10 cm) O.D. single wall pipe may be attached to the heater. The duct may be up to 45 ft. (13.7 m) maximum length or 2 ft. (60 cm) minimum length with no more than 2 elbows. See Vent Length Requirements heading on pg. 22 for more detailed guidelines. The air supply duct may have to be insulated to prevent condensation on the outer surface. The outside air terminal should be securely fastened to the outside wall by drilling four 1/4" (6 mm) diameter holes in the outside flange; wood screws or bolts and expansion sleeves may be used to fasten the terminal. For the outside air ter minal, use the Vent Cap (P/N 90502300) that is provided with the VANTAGE® H E heater. PVC pipe, aluminum flex duct, or equivalent may be used instead of single wall pipe for the outside combustion air supply.

Non-Pressurized Outside Air Supply for a Maximum of Two Heaters Controlled by a Common Thermostat OUTSIDE COMBUSTION AIR SUPPLY (CONTINUED) When air is supplied for combustion to a maximum of two heaters through a common duct, the following rules apply: 1. Follow the venting rules on page 22 for detailed guidelines. 2. The two units must be controlled by a common thermostat. 3. Use 4'' O.D. (10 cm O.D.) single wall or PVC pipe between the heater connection and the common source. The common source will be a minimum of 6'' O.D. (15 cm O.D.) single wall or PVC pipe. 4. Combined length of the 4'' (10 cm) and 6'' (15 cm) pipe shall not exceed 45 ft. (13.7 m) with 2 elbows maximum per unit (see Fig. 28). See also Vent Length Requirements heading on page 22 for more detailed guidelines. 5. Entry of the 4'' (10 cm) pipes will not oppose one another. Example: 4 ft. of 6" O.D. (1.2 m of 15 cm O.D.) common supply air pipe and one 6''x4''x4'' tee are attached to a 4'' pipe x 4 ft. long, attached to VANTAGE® H E units. This will limit the flue length to 45 ft. of 4'' (13.7 m of 10 cm) pipe. pg 30 VA N TA G E ® HE ROBERTS-GORDON I N S TA L L AT I O N M A N U A L Section 9.

Flex gas line can crack when twisted. Failure to follow these instructions can result in death, injury or property damage. Gas line moves during normal operation. Failure to follow these instructions can result in death, injury or property damage. Follow these instructions to ensure a professional gas supply system installation: • Support all gas piping with suitable pipe hanging materials. • Use wrought iron or wrought steel pipe and malleable iron fittings. All pipe and fittings should be new and free from defects. Carefully ream the pipe and tubing ends to remove obstructions and burrs. • Use LP-gas-resistant joint compound on all threads. Read applicable warnings in Section 1 before proceeding with Gas Piping installation. Meter and service must be large enough to handle all the burners being installed plus any other connected load. The gas line which feeds the system must be large enough to supply the required gas with a maximum pressure drop of 1/2" (1.3 cm) w.c. When gas piping is not included in the layout drawing the local gas supplier will usually help in planning the gas piping. Shut-Off Valve (included w/ connector) A 1/2" (1.3 cm) gas supply connection at each burner location must be located and oriented as shown in Figure 27. To check system pressure, put a plugged 1/8" (3 mm) NPT tapping in the gas line at the connection to the burner furthest from the supply.

Maintenance For best performance, the following maintenance procedures should be performed before each heating season: 1. Be sure gas and electrical supply to heater are off before performing any service or maintenance. 2. Check condition of blower scroll and motor. Dirt and dust may be blown out with compressed air, or a vacuum cleaner may be used. No contient aucune pièce réviasble par l'utillisateur. 3. Check condition of burner. Carefully remove any dust or debris from inside the burner box or burner cup. Le non-respect de ces consignes peut causer mort, blessures ou dommage matériel. 4. Inspect the igniter. Replace igniter if there is excessive carbon residue, erosion, breakage or other defects. The VANTAGE® HE heater is equipped with a hot-surface ignition system. Sequence of Operation 1. Turn the thermostat up. When the thermostat calls for heat, the SmartValve ® II will energize. After a short period, power is supplied to the blower motor. 2. When the motor approaches nominal running RPM, the pressure switch closes and signals the ignition module/SmartValve® II. 3. The ignition module/SmartValve® II then energizes the hot surface igniter for a timed war m-up period (approximately 45 to 60 seconds). 4. After the warm-up period, the gas valve is energized. 5. The flame will be sensed by the flame sensing rod and the igniter is de-energized. 6. If a flame is detected, the gas valve remains open. When the call for heat is satisfied, and the system control mechanism de-energizes the burner line voltage supply, the gas valve is turned off. 7. If no flame is detected on the module, the gas valve is closed, and a purge period begins. After the purge, the module acts to power the igniter for a second warm up period, and a second trial for ignition period. If flame is still not established, a third purge, warm up, and trial cycle begins. After four trials, the module will lockout until reset. Reset is accomplished by removing power from the module for at least 5 seconds (thermostat cycle required). 5. Check the inside of the firing tube with a flashlight. If carbon or scale are present remove the turbulator(s). Scrape out the deposits with a wire brush or rod, or metal plate attached to a wooden pole and replace turbulator(s) in tube. 6. Check to see that the burner observation window is clean and free of cracks or holes. Clean or replace as necessary. 7. Check the flue pipe for soot or dirt. After cleaning as necessary, re-attach the flue pipe to the heater. 8. Outside surfaces of heater reflector may be cleaned by wiping with a damp cloth. 9. A qualified service agency should be contacted for service other than routine maintenance. 10. Check vent terminal and fresh air inlet to see that they have not become blocked during the non-heating season. If either pipe is restricted, the pressure switch won’t close, resulting in a no-heat situation. Outdoor 1. Clean any debris from top of tubes and reflectors. 2. Check for evidence of animals such as squirrels or birds and remove any nests prior to firing. pg 36 VA N TA G E ® HE I N S TA L L AT I O N M A N U A L ROBERTS-GORDON Section 12.
